Article Information

A modified USP paddle method using minibaskets was used to study the effects of various formulations on in vitro dissolution of ibuprofen microspheres. Formulations containing waxes such as paraffin or ceresine wax without modifiers exhibited very slow dissolution profiles and incomplete release, which did not improve with increased drug loading or the preparation of smaller microspheres. Higher drug loading and decreased microsphere size increased the dissolution rate from microspheres containing modifier. An increase in the encapsulation dispersant concentration had little effect on the dissolution profiles. With appropriate modifiers, wax microsphere formulations of drugs with solubility characteristics similar to those of ibuprofen can offer a starting basis for predictable sustained release dosage forms.

Shailesh T. Prajapati, Amit N. Patel, Chhagan N. Tablets were prepared by melt granulation technique and evaluated for various evaluation parameters. Controlled-release CR formulations have been introduced into drug therapy with two main purposes: to reduce the number of single doses per day improving patient compliance of treatments and to decrease the fluctuations of plasma levels, in order to obtain better therapeutic efficacy and lower toxicity.

Pharmacy College, Paloncha - , Telangana, India. ABSTRACT: The objective of the present study is to develop a pharmaceutically stable sustained release matrix tablets of Baclofen and perform the pre-compression, post compression and in-vitro evaluation studies of developed formulation. All the formulations have showed acceptable Pharmacopeial standards. Formulation F9 have extended the release of Baclofen upto 12 h. Model fitting analysis for formulation F9 fitted in the zero order model and korsemeyer- peppas model. Sustained release technology is relatively new field and as a consequence, research in the field has been extremely fertile and has produced many discoveries. With many drugs, the basic goal is to achieve a steady state blood level that is therapeutically effective and non-toxic fir an extended period of time.

Formulation and Evaluation of Sustained Release Matrix Tablets of Repaglinide

Rabeprazole, a member of substituted benzimidazoles, inhibits the final step in gastric acid secretions. This drug claims to cause fastest acid separation due to higher pKa , and more rapidly converts to the active species to aid gastric mucin synthesis. The most significant pharmacological action of Rabeprazole is dose dependent suppression of gastric acid secretion; without anticholinergic or H2-blocking action. It completely abolishes the hydrochloric acid secretion as it is powerful inhibitor of gastric acid.

Methods: The ibuprofen matrix tablets were prepared by direct compression method using lactose as a diluent. Nineteen formulations of different polymer percentages were formulated, F1-F19 with 7. The formulation exhibited highest correlation R value in case of Hixson-Crowell model and the release kinetic study proved that the formulation showed erosion process, and shown to follow zero order kinetics. Conclusion: It was concluded that eudragit RL can be used for the preparation of sustained release tablet of ibuprofen.

Conventional drug delivery system for treating the angina and hypertension are not much effective as the drug do not reach the site of action in appropriate amounts. Thus potent and guarded therapy of this angina and hypertension disorder using specific drug delivery system is a challenging task to the pharmaceutical professionals. Most oftenly used method of regulating the drug release is to include it in a matrix system because of their pliability, hydrophilic polymer matrices are widely used in oral controlled drug delivery to obtain a desirable drug release pattern, methodical, and broad regulatory compliance. Formulation of Nifedipine sustained release matrix tablet was prepared by the polymers blend with to get desirable drug release profile. Evaluation parameters of formulated tablets were hardness, friability, thickness, drug content uniformity weight variation, and the in vitro drug release rate pattern.

The aim of present investigation was to formulate and evaluate the sustained release matrix tablets of Repaglinide RPGN. Invitro drug release studies were performed by USP dissolution apparatus type-II paddle method using 0. Amongst all the 12 formulations, formulation F12 showed maximum drug release of It was observed from the kinetic studies that all the formulations followed first order kinetics and particularly the drug release from its dosage form was fickian diffusion F9, F12 , non-fickian diffusion F1-F8, FF Formulation F12 was subjected to stability studies and confirmed that formulation F12 was stable upto the period of 1 month.

Энсей Танкадо - это Северная Дакота… Сьюзан попыталась расставить все фрагменты имеющейся у нее информации по своим местам. Если Танкадо - Северная Дакота, выходит, он посылал электронную почту самому себе… а это значит, что никакой Северной Дакоты не существует. Партнер Танкадо - призрак. Северная Дакота - призрак, сказала она. Сплошная мистификация. Блестящий замысел. Выходит, Стратмор был зрителем теннисного матча, следящим за мячом лишь на одной половине корта.

Однако тот не подавал никаких признаков жизни. Сьюзан перевела взгляд на помост перед кабинетом Стратмора и ведущую к нему лестницу. - Коммандер. Молчание. Тогда она осторожно двинулась в направлении Третьего узла. Подойдя поближе, она увидела, что в руке Хейла зажат какой-то предмет, посверкивавший в свете мониторов.

Люди на соседних койках приподнялись и внимательно наблюдали за происходящим. В дальнем конце палаты появилась медсестра и быстро направилась к. - Хоть что-нибудь, - настаивал Беккер. - Немец называл эту женщину… Беккер слегка потряс Клушара за плечи, стараясь не дать ему провалиться в забытье. Глаза канадца на мгновение блеснули. - Ее зовут… Не отключайся, дружище… - Роса… - Глаза Клушара снова закрылись. Приближающаяся медсестра прямо-таки кипела от возмущения.

Она взглянула на скоростное печатное устройство позади письменного стола шефа. В нем ничего не. - Сьюзан, - тихо сказал Стратмор, - с этим сначала будет трудно свыкнуться, но все же послушай меня хоть минутку.  - Он прикусил губу.

На мгновение ей показалось, что на нее были устремлены горящие глаза Хейла, но прикосновение руки оказалось на удивление мягким. Это был Стратмор. Лицо его снизу подсвечивалось маленьким предметом, который он извлек из кармана. Сьюзан обмякла, испытав огромное облегчение, и почувствовала, что вновь нормально дышит: до этого она от ужаса задержала дыхание.

Фонтейн сурово взглянул на. Уж о чем о чем, а о стрессовых ситуациях директор знал. Он был уверен, что чрезмерный нажим не приведет ни к чему хорошему. - Расслабьтесь, мистер Беккер. Если будет ошибка, мы попробуем снова, пока не добьемся успеха.

 Электроснабжение уже наверняка восстановили.  - Он открыл жалюзи. - Все еще темно? - спросила Мидж. Но Бринкерхофф не ответил, лишившись дара речи. То, что он увидел, невозможно было себе представить.

Беккер рванулся. Вобрав голову в плечи, он ударил убийцу всем телом, отшвырнув его на раковину.
